摘要:電力系統中高壓開關柜的一次開關設備工作狀態、溫濕度控制、高壓帶電指示等功能一般是由信號燈和獨立的電氣元件實現的,這勢必會帶來集成度低、配線復雜、可靠性差的缺點。本文介紹了一種開關柜智能測控裝置,適用于3~35kV戶內高壓開關柜,用于一次開關設備狀態模擬顯示、高壓帶電指示、防凝露溫濕度控制、電參數測量等,大大提高了開關柜操控和測顯的集成度和智能化程度。

Abstract: According to the survey, working state of the switching device, control of temperature and humidity and high-voltage live instruction are usually achieved by some signal lamps and several independent electronic devices in a high-voltage switchboard of power system, which will inevitably bring about the shortcomings of low integration, complex wiring, and lower reliability. An intelligent monitoring and control device for switchboard named ASD is introduced in this paper, which is used in 3 ~ 35kV indoor high voltage switchboard. The device is used for the indicate of switching device status, high-voltage live instructions, anti-condensing temperature and humidity control, electrical parameter measurement and so on, which is highly increased the integration and inligence of manipulation and measurement of the switchboard.

開關柜一般有斷路器(負荷開關)、隔離刀閘、接地刀閘等一次開關設備。在運行或調試中,監測這些一次開關設備狀態是至關重要的。在傳統的開關柜上,一般使用信號燈來指示這些狀態的,這樣做顯示不直觀,且接線不方便。開關柜智能測控裝置將一次設備狀態顯示與開關柜的一次方案圖相結合,LED顯示器件置于一次方案圖中設備符號所處位置,電路狀態一目了然,生動直觀
